Abstract (en)
[origin: EP4059801A1] Generally, an impact absorbing device is proposed. More particularly, the impact absorbing device is mounted to a railroad car coupler, to a buffer stop installed at an end of a railroad track, or to side buffers provided at opposite sides of an end part of a railroad car and doubly absorbs impact during the application of the impact thereto such that impact occurring during the coupling of railroad cars to each other and large impact occurring during collision of railroad cars can be absorbed, and has an overall simple structure such that the impact absorbing device is easily attached to and detached from the railroad car coupler, the buffer stop installed at an end of a railroad track, or the side buffers provided at opposite sides of an end part of a railroad car, so maintenance costs of the impact absorbing device can be reduced.
